A World of Advantages With Canon's New Technology.

DIGIC 4 Image Processor
Canon's proprietary DIGIC Image Processors have long set its cameras apart from the competition, and the new DIGIC 4 sets the bar even higher. Faster, more accurate noise reduction delivers better image quality, even at high ISO speeds.

DIGIC 4 Image Processor

iSAPS Technology is an entirely original scene-recognition technology developed for digital cameras by Canon. Using an internal database of thousands of different photos, iSAPS works with the advanced DIGIC 4 Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

A new Face Self-Timer automatically detects an increase in the number of faces and makes the appropriate adjustments. For instance, to include photographer's face in a group shot, there's no need to rush in. Just put the camera on a stand or tripod, and specify Face Self-Timer, and the camera will wait for the photographer's face to get on-camera before it takes the shot. Motion Detection now tracks moving subjects in a much larger range, and the new Servo AF retains focus on a moving subject after the shutter button is pressed halfway - allowing you to wait for the perfect shot without refocusing. Also, Face Detection and Motion Detection are markedly improved.

Intelligent Contrast Correction
DIGIC 4 also makes possible the new i-Contrast (Intelligent Contrast Correction) system, which controls the compensation level in pixel units to brighten dark areas while leaving bright areas unchanged for better images where the main subject is dark, and more natural transition. The PowerShot SD990 IS Digital ELPH can even use i-Contrast in playback mode to adjust images that were shot without the setting activated.

Red-eye Correction provides three options for removing red-eye from subjects in flash pictures.
1) The Red-eye Correction during shooting actually identifies and corrects red-eye in human subjects as pictures are taken.
2) The SD990 IS Digital ELPH can be set to automatically detect and correct red-eye during image playback.
3) You can manually locate any red eyes in a scene during image playback on the LCD screen, and command the camera to remove them.

Life doesn't give you second chances to capture special times. That's why the SD990 IS Digital ELPH features ISO 1600 and High ISO Auto settings that reduce the effects of camera shake and sharpen subjects in low-light situations, giving you greater shooting flexibility. ISO can be expanded to 3200 when you select ISO 3200 Special Scene mode.
